Abstract

"PROCESSO E SISTEMA PARA MEDIDA DA DURAçãO EM QUE UMA áREA ESTá INCLUìDA EM UM FLUXO DE IMAGEM". Um sistema e um processo para cálculo da duração de uma área alvo, incluída dentro de um fluxo de imagem, utiliza um modelo tridimensional de pelo menos um alvo dentro de um local. Um contador é incrementado durante períodos, por exemplo, em uma base quadro a quadro, quando a área alvo é incluída no fluxo de imagem. Um parâmetro de oclusão é calculado para ajuste da duração calculada, que a área alvo é incluída dentro do fluxo de imagem. O parâmetro de inclusão facilita a consideração para as variações em uma obstrução da área alvo, e é usado para fazer ajustes em um contador, de modo que uma contagem indicativa de uma duração reflete as variações nas obstruções da área alvo. Um parâmetro de primeiro plano, associado com a área alvo, é calculado para ajuste da duração calculada da área alvo. O parâmetro de primeiro plano facilita a consideração das variações na visibilidade de uma imagem incluída dentro da área alvo, resultantes dos vários zuns da câmara.
